A method of producing a fiber-reinforced resin-molded member includes: preparing a mold including an upper mold and a lower mold forming a cavity, a cavity surface of either the upper mold or the lower mold being provided with a projecting portion; disposing a fiber-reinforcing material in the cavity, closing the molds to generate a state in which the projecting portion presses a part of the fiber-reinforcing material, and filling the cavity with a melted resin to impregnate the fiber-reinforcing material with the melted resin and cure the melted resin; and opening the molds to obtain a fiber-reinforced resin-molded member having an exposed portion and an embedded portion. The exposed portion includes at least a portion pressed by the projecting portion while the molds are closed.

A fastening structure is fastened to an object. The fastening structure includes a carbon fiber-reinforced resin, a metal collar and a fastener. The outer circumference of a metal collar has a tapered portion, which is inclined with respect to the central axis of the collar. The inner circumferential surface of a through hole in a carbon fiber-reinforced resin (CFRP) material has an abutting portion that contacts the tapered portion of the collar via an electrically insulating adhesive. The tilt angle of the tapered portion of the collar and of the abutting portion of the CFRP material are the same as the angle at which the displacement of the CFRP material in a direction perpendicular to the surface of the abutting portion due to thermal deformation resulting from temperature changes is balanced with the displacement of the collar in a direction perpendicular to the surface of the tapered portion.

An object is created by a more appropriate method when the object is created by combining pieces. A method of manufacturing a product is provided, in which a product 50 for use as a piece is manufactured when a three-dimensional object 40 is created. The product 50 is built by adding layers of an ink. The product 50 includes a surface region 202, an end region 204, and an interior region 206. At least a part of the surface region 202 is formed in a colored state using a coloring ink. At least a part of the interior region 206 is formed as a light-reflective region using a light-reflective ink. At least a part of a portion along an edge portion 210 of the surface region 202 in the end region 204 is formed in a colored state using a coloring ink.

A composite housing and a method of assembling a composite housing for a scanning assembly. A body of the housing defines an opening of a first perimeter. A polymethylpentene scanning plate is provided which has lip with a marginally larger perimeter than the first perimeter. During assembly of the composite housing, at least a part of scanning plate is thermally contracted to allow it to be positioned within the opening such that the peripheral side surface of the scanning surface faces the edge of the body. When the scanning plate returns to ambient temperature and expands at least a portion of the side surface of the scanning plate engages the edge of the body.

A method of joining polymer components includes additively manufacturing first and second mating features on first and second polymer components such that a mechanical lock is created through undercut geometric features of an adhesive material when the polymer components are joined. Adhesive is added between the mating components to strengthen the joint.

A method of forming a joint between a composite component and a metallic component is disclosed. The method includes forming a first groove in an outer surface of the metallic component on a first end of the metallic component. The first groove extends circumferentially on the outer surface relative to a center axis of the metallic component, and the first groove extends radially inward from the outer surface relative the center axis. The method further includes inserting the first end of the metallic component into a first end of the composite component. A second groove on the composite component over the first groove of the metallic component such that the composite component extends radially inward into the first groove of the metallic component. A composite hoop reinforcement is then applied in the second groove in a circumferential direction and the composite component, and the composite hoop reinforcement are solidified.

A fastening structure is fastened to an object. The fastening structure includes a carbon fiber-reinforced resin, a metal collar and a fastener. The outer circumference of a metal collar has a tapered portion, which is inclined with respect to the central axis of the collar. The inner circumferential surface of a through hole in a carbon fiber-reinforced resin (CFRP) material has an abutting portion that contacts the tapered portion of the collar via an electrically insulating adhesive. The tilt angle of the tapered portion of the collar and of the abutting portion of the CFRP material are the same as the angle at which the displacement of the CFRP material in a direction perpendicular to the surface of the abutting portion due to thermal deformation resulting from temperature changes is balanced with the displacement of the collar in a direction perpendicular to the surface of the tapered portion.

A composite structural component includes a longitudinally extending elongated tubular duct of a first material having a first coefficient of thermal expansion, and a plurality of longitudinally extending elongated reinforcing members of a second material. Each of the reinforcing members is secured to the tubular duct along a length of the reinforcing member at spaced apart locations on the tubular duct, with the second material having a second coefficient of thermal expansion less than the first coefficient of thermal expansion, such that the composite structural component has an effective coefficient of thermal expansion in the longitudinal direction that is less than 25% of the first coefficient of thermal expansion. Each of the plurality of reinforcing members is retained in a corresponding one of a plurality of longitudinally extending recesses formed in a peripheral wall of the tubular duct.

This specification discloses an article of manufacture. The article of manufacture has at least one structural blank and at least one guide. The structural blank has a plurality of oriented fiber plies in a thermoplastic matrix. The guide has a plurality of random dispersed fibers in a thermoplastic matrix. The guide is affixed to the structural blank by injection molding and over molding the guide onto the structural blank. The article of manufacture can take a number of forms for use in industries such as aircraft, automobiles, motorcycles, bicycles, trains or watercraft.

A method of fastening an edge structure to a construction element includes providing the construction element, being a planar structure with with two cover regions and a middle region between the cover regions; providing the edge structure being continuously extended, the edge structure having contact surfaces with a thermoplastic material shaped to lie against the cover regions in an outer surface of the construction element, and, opposite the contact surfaces, a coupling-in surface for coupling energy into the edge structure; coupling energy into the edge structure and pressing the contact surfaces against the cover regions until at least a portion of the thermoplastic material is liquefied and pressed into the cover regions; and repeating or continuing the steps of coupling and pressing until the edge structure is attached to the building element at a plurality of discrete locations or over an extended region along an edge of the construction element.
